303.04.0036.04 Compatible ECAS Solenoid Valve Kit

What does an ECAS repair kit do?

This ECAS solenoid valve repair kit is a service set designed to renew the worn elements inside the solenoid valve blocks of an electronically controlled air suspension system. By replacing internal components, technicians can restore the precise air flow required to maintain constant chassis height. These kits are engineered for high-durability performance in demanding environments.

Vehicle and engine compatibility

The kit is compatible with WABCO systems and is fitted to Volvo and Mack trucks, including models like the Volvo FH13, FM12, and Mack Granite. It provides a cost-effective solution for maintaining the electronic suspension control of various heavy commercial vehicles, ensuring reliable operation of the air bellows through accurate filling and venting cycles.

Installation and maintenance

During maintenance, it is essential to inspect the valve block for any debris that might have bypassed the filter. When installing this kit, ensure that all sealing elements are seated correctly to prevent air leaks or delayed level response. This service allows for the refurbishment of the existing block rather than a full component replacement.

Troubleshooting suspension response

If you observe the vehicle sagging while parked or experience delayed height adjustments, a complete inspection of the ECAS solenoid assembly is recommended to identify specific wear points within the valve block.
